The power thumbs up (PTU) is my favorite of all thumbs up variants. One of the keys of the PTU is a hard stop - similar to an effective casting stroke, you really need to accelerate into a hard stop. The beauty of the PTU is that it can be supplemented with a wink or a nod to really convey approval at that next/higher level.
Some text book examples of the power thumbs up from some of the greatest out there - note the acceleration into the hard stop.
